Question

Can I get a little help? Confused by the question.

Answer 1

The density of the sphere is 0.2g/ml .

Given the mass of the ball = 20 g

Original water volume = 50 ml

The final volume level of water =150 ml

So the volume of the ball = volume displaced in the water

= 150 mo - 50 ml

= 100 ml

and density = mass / volume

therefore the density of the sphere is m/v = 20/100 or 0.2 g/ml

What is the density of a sphere?

You can determine the value of m once you have weighed the relevant sphere. All that is left to do is determine its volume (V), which you can do by determining its diameter (d). The density equation is  m / V.
